Description

Method and apparatus for controlling Discontinuous Reception (DRX)

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling Discontinuous Reception (DRX).

Background

Discontinuous Reception (DRX) is intended for terminal devices to save power, and terminal devices in the DRX state do not need to continuously monitor the control channel. However, if the terminal device does not listen to the control channel for a long time, the delay of data transmission will be increased once data arrives. In order to take the remaining points and the transmission delay into account, according to the length of time for the terminal device to monitor the channel, a New Radio (NR) Medium Access Control (MAC) supports two DRX cycles, a DRX long cycle and a DRX short cycle.

If the network equipment predicts that the data volume of the terminal equipment is more frequent or the service is more sensitive to time delay, the network equipment can configure the terminal equipment to use a DRX short cycle; if the data volume of the terminal equipment is predicted to be sparse and the time delay is not sensitive, the network equipment can configure the terminal equipment to use the DRX long cycle. Although the prior art can realize that the terminal device switches between the DRX long cycle and the DRX short cycle, the DRX configuration related to the DRX long cycle and the DRX short cycle is a set DRX configuration. This will make the terminal device not only able to switch between the DRX long cycle and the DRX short cycle, but also unable to dynamically adjust other parameters used when performing DRX operation, which limits the power saving performance of the terminal device.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 illustrates a method of controlling DRX according to one embodiment of the present application. The method shown in fig. 1 may be performed by a terminal device. As shown in fig. 1, the method comprises:

s110, receiving a first medium access control unit MAC CE.

S120, if the value of the LCID domain of the logical channel identifier corresponding to the first MAC CE is a first preset value, or the value of the LCID domain corresponding to the first MAC CE is the first preset value and the value of the corresponding reserved bit is a second preset value, determining a target DRX configuration to be activated according to the first MAC CE, wherein the target DRX configuration is one of M sets of DRX configurations, and M is an integer greater than or equal to 2.

The M sets of DRX configurations in S120 may be configured by the network device to the terminal device through Radio Resource Control (RRC) signaling. The first MAC CE in S120 may be understood as DRX Activation Command (DRX Activation Command) or DRX change Command (DRX change Command).

The parameters in each of the M sets of DRX configurations include, but are not limited to, the following parameters: drx-LongCycleStartOffset: a cycle and an offset for configuring the long DRX cycle, the unit of the cycle and the offset being milliseconds; drx-short cycle: a cycle and an offset for configuring the short DRX cycle, the unit of the cycle and the offset being milliseconds; drx-ShortCycleTimer: the unit of the time length used for controlling the terminal equipment to use the short DRX period is an integer, and the time length indicates that the terminal equipment needs to maintain the integral multiple of the short DRX period once entering the short DRX period; drx-onDurationTimer: the DRX continues to monitor a timer, during which the terminal device needs to continuously monitor a Physical Downlink Control Channel (PDCCH) of the network. The timer unit is milliseconds; drx-slotofset: the terminal starts the time delay of drx-onDurationTimer; drx-inactivytytimer: a DRX inactivity timer; drx-HARQ-RTT-TimerDL: a Round-Trip Time (RTT) timer for a Hybrid Automatic Repeat request (HARQ); drx-HARQ-RTT-timerll: an uplink HARQ RTT timer; drx-retransmission timerdl: a downlink retransmission timer; and, drx-retransmission timerrul: and an uplink retransmission timer.

As an example, in S120, determining a target DRX configuration to be activated according to the first MAC CE includes: if the first MAC CE does not carry the load part, determining that the target DRX configuration is a default DRX configuration in the plurality of sets of DRX configurations; or, if the first MAC CE carries a load part, determining a target DRX configuration according to the load part.

It can be understood that, in the case that the first MAC CE does not carry a payload part, signaling overhead can be saved.

For example, the first MAC CE has the structure shown in fig. 2, and a value of the LCID field corresponding to the first MAC CE is a first preset value, which indicates that the type of the first MAC CE is a first type. Since the first MAC CE shown in fig. 2 does not carry any DRX configuration indication, the first MAC CE shown in fig. 2 may be used to activate a default DRX configuration. Here the default DRX configuration may be configured by RRC signaling. And if the terminal equipment is in the DRX deactivation state currently, the terminal equipment activates default DRX configuration. If the terminal device is currently in a DRX active state (or it is understood that the terminal device is performing DRX operation using a set of DRX configurations), the terminal device switches (Change) the DRX configuration being used to a default DRX configuration.

Under the condition that the first MAC CE carries the load part, the terminal device may determine, according to the load part, an implementation manner of the target DRX according to the load part, which includes the following several manners:

the first method is as follows:

and the load part carries configuration identification indication information, and the configuration identification indication information is used for indicating the DRX configuration identification. In this case, the DRX configuration identifier is identified as the corresponding DRX configuration, and is determined as the target DRX configuration.

For example, the format of the first MAC CE is shown in fig. 3. The LCID field of the first MAC CE indicates that the type of the first MAC CE is DRX Active/Change Command, the load part bears DRX index, and the terminal equipment determines that the target DRX is the DRX configuration indicated by the DRX index after receiving the first MAC CE. And if the terminal equipment is currently in the DRX deactivation state, the terminal equipment activates the DRX configuration indicated by the DRX index. If the terminal device is currently in a DRX active state (or it is understood that the terminal device is performing DRX operation by using a set of DRX configuration), the terminal device switches (Change) the DRX configuration being used to the DRX configuration indicated by the DRX index.

The second method comprises the following steps:

each set of DRX configuration comprises N sets of sub-configurations, and meets the condition that part of DRX configuration comprises N sets of sub-configuration identification indication information, each set of sub-configuration identification indication information is used for indicating one sub-configuration identification, and N is an integer greater than or equal to 2. In this case, the terminal device determines the DRX configuration including the sub-configuration corresponding to the target sub-configuration identifier as the target DXR configuration, where the target sub-configuration identifier is the sub-configuration identifier indicated by the N sub-configuration identifier indication information.

For example, the format of the first MAC CE is as shown in fig. 4. The LCID field of the first MAC CE indicates that the type of the first MAC CE is DRX Active/Change Command, the load part carries 2 DRX indexes 1 and DRX indexes 2, and the terminal equipment determines that the target DRX configuration is the DRX configuration comprising the sub-configurations indicated by the DRX indexes 1 and DRX indexes 2 after receiving the first MAC CE. And if the terminal equipment is in the DRX deactivation state currently, the terminal equipment activates the sub-configurations indicated by the DRX index1 and the DRX index 2. If the terminal device is currently in a DRX active state (or it is understood that the terminal device is performing DRX operation using a set of DRX configurations), the terminal device switches (Change) the sub-configuration in use to the sub-configurations indicated by DRX index1 and DRX index 2.

As an example, all DRX parameters included in a set of DRX configurations may be divided into two sets, where the parameters in each set form a set of sub-configurations, one set is related to the traffic burst characteristics, such as the period related parameters and DRX-onDurationTimer, DRX-inactivytytimer, and the other set is related to the transmission, such as DRX-HARQ-RTT-timerls, DRX-retransmission timerls, and the like. The two types of parameter sets are configured and marked independently, and the terminal equipment can determine the activated parameter complete set through two indexes in the load part carried by the first MAC CE.

The third method comprises the following steps:

the load part carries a bitmap with a degree of K, where K is an integer greater than or equal to M. In this case, the terminal device determines the DRX configuration corresponding to the target bit in the bitmap as the target DRX configuration, where the value of the target bit is a first target value, and the first target value is different from the values of other bits.

It is understood that in the third case, the order of the bits in the bitmap may represent the order of the DRX configurations appearing in the RRC signaling, for example, the first bit in the bitmap represents the first set of DRX configurations appearing in the RRC signaling, the second bit in the bitmap represents the second day DRX configurations appearing in the RRC signaling, and so on.

For example, the format of the first MAC CE is as shown in fig. 5. The LCID field of the first MAC CE indicates that the type of the first MAC CE is DRX Active/Change Command, the payload part carries bitmap including 8 bits (I0-I7), I0 represents a first set of DRX configuration in RRC signaling, I1 represents a second set of DRX configuration in RRC signaling, and so on. If the value of I0 in bitmap in fig. 5 is 1 and the values of other bits are 0, the terminal device determines that the target DRX configuration is the first DRX configuration in the RRC signaling. If the terminal device is currently in the DRX deactivation state, the terminal device activates a first set of DRX configurations, and if the terminal device is currently in the DRX activation state (or it is understood that the terminal device is performing DRX operation using one set of DRX configurations), the terminal device switches (Change) the sub-configuration in use to the first set of DRX configurations.

The method four comprises the following steps:

each set of DRX configuration comprises L sets of sub-configurations, a load part bears L bitmap, each bitmap corresponds to one set of sub-configurations, and L is a positive integer greater than or equal to 2. Under the condition, the terminal equipment determines DRX configuration corresponding to the L set of sub-configuration according to the L bitmaps; combining the DRX configurations of the L set of sub-configurations into the target DRX configuration; the method for determining the DRX configuration corresponding to the L set of configuration according to the L bitmaps comprises the following steps: and determining the DRX configuration corresponding to the target bit of the ith bitmap as the DRX configuration of the ith sub-configuration, wherein the value of the target bit is a second target value, and the second target value is different from the values of other bits in the ith bitmap, i =1, \8230l.

For example, the format of the first MAC CE is as shown in fig. 6. The LCID field of the first MAC CE indicates that the type of the first MAC CE is DRX Active/Change Command, the load part carries 2 bitmaps including 4 bits, and the mark is as follows: j-domain and I-domain. The sequence of bits in the J domain and the I domain represents the sequence of the DRX configurations corresponding to the sub-configurations appearing in the RRC signaling, for example, I0 represents the DRX configuration corresponding to the first set of sub-configurations in the RRC signaling sub-configuration set 1, I1 represents the DRX configuration corresponding to the second set of sub-configurations in the RRC signaling sub-configuration set 1, J0 represents the DRX configuration corresponding to the first set of sub-configurations in the sub-configuration set 2, J1 represents the DRX configuration corresponding to the second set of sub-configurations in the sub-configuration set 2, and so on. If the value of I0 is 1, the values of I1-I3 are all 0, the value of J1 is 1, and the values of J0 and J2-J3 are 0, if the terminal device is currently in the DRX deactivation state, the terminal device activates the DRX configuration corresponding to the first set of sub-configuration in the sub-configuration set 1, and activates the DRX configuration corresponding to the second set of sub-configuration in the sub-configuration set 2. If the terminal device is currently in a DRX active state (or it is understood that the terminal device is performing DRX operation using one set of DRX configurations), the terminal device switches (Change) the sub-configuration in use to the DRX configuration corresponding to the first set of sub-configurations in the sub-configuration set 1 and the DRX configuration corresponding to the second set of sub-configurations in the sub-configuration set 2.

On the basis of all the above embodiments, if the terminal device is in the DRX deactivation state at the receiving time of the first MAC CE, the method shown in fig. 1 further includes: performing a DRX operation according to the target DRX configuration from a start time of a first active period after a reception time of the first MAC CE; or, at the time of receiving the first MAC CE, performing DRX operation according to the target DRX configuration.

In other words, if the terminal device is in the DRX-deactivated state at the reception time of the first MAC CE, the terminal device may perform the DRX operation from the next most recent activation period (On Duration) start position. Or, the terminal equipment executes the DRX operation immediately after receiving the first MAC CE. And the terminal equipment executes corresponding operation according to the target DRX configuration in which period currently. For example, if the On Duration is in the On Duration, the PDCCH is monitored, and if the On Duration is not in the On Duration, the PDCCH is not monitored until the next On Duration wakes up to monitor the PDCCH. Here, the behavior of the terminal device may be agreed by a protocol, or may be indicated by the network device through MAC signaling display, for example, the network device may add 1bit in the first MAC CE to additionally indicate the behavior of the terminal device, or the network device indicates the behavior of the terminal device through a special MAC CE.

On the basis of all the above embodiments, if the terminal device is in the DRX active state at the receiving time of the first MAC CE, the method shown in fig. 1 further includes: starting to execute DRX operation according to the target DRX configuration from the first DRX period after the current DRX period is finished; or, at the time of receiving the first MAC CE, performing DRX operation according to the target DRX configuration.

In other words, if the terminal device is in DRX active state at the reception time of the first MAC CE, the terminal device may keep the current DRX cycle still executing according to the old parameters, keep the respective DRX timers that are currently running active, and enlighten the target DRX configuration from the next DRX cycle. Or, after receiving the first MAC CE, the terminal device immediately abandons the old DRX configuration and stops all DRX timers, or only stops timers related to active activation, such as DRX-on duration timer and DRX-inactivity timer, and then recalculates the state that should be in according to the target DRX configuration, such as whether the terminal device should be in an on duration state, that is, the terminal device immediately performs DRX operation using the new DRX configuration. Here, the behavior of the terminal device may be agreed by a protocol, or may be indicated by the network device through MAC signaling display, for example, the network device may add 1bit in the first MAC CE to additionally indicate the behavior of the terminal device, or the network device indicates the behavior of the terminal device through a special MAC CE.

Optionally, as an embodiment, the method shown in fig. 1 further includes: and if the value of the LCID domain corresponding to the first MAC CE is a third preset value, or the value of the LCID domain corresponding to the first MAC CE is the first preset value and the value of the corresponding reserved bit is a fourth preset value, deactivating the DRX configuration in use and entering a continuous monitoring state, wherein the DRX configuration in use is one of the M sets of DRX configurations.

The first MAC CE here may also be understood as DRX Deactivation Command (DRX Deactivation Command). Generally, the terminal device is in a data intensive period or the transmission delay requirement of data is high (for example, ultra-low delay and/or ultra-high reliability), or the terminal device reports that the requirement for power saving does not need to consider power saving, and tries to ensure the quality of service transmission, under these circumstances, the network device may consider to deactivate the DRX configuration of the terminal device, so that the terminal device may continuously monitor the PDCCH, and obtain a better data transmission guarantee.

It can be understood that, under the condition that the value of the LCID field corresponding to the first MAC CE is the first preset value and the value of the Reserved bit corresponding to the first MAC CE is the fourth preset value, it indicates that the DRX Activation Command and the DRX Deactivation Command may multiplex one LCID value, and at this time, a Reserved (R) bit of the header is used to additionally indicate whether the first MAC CE is the Activation Command or the Deactivation Command.

As another example, the method shown in fig. 1 further includes:

and if the value of the LCID domain corresponding to the first MAC CE is a first preset value, and the load part carried by the first MAC CE, the DRX configuration identifier indicated by the carried configuration identifier indication information and the configuration identifier of the M sets of DRA configurations are different, deactivating the DRX configuration in use and entering a continuous monitoring state, wherein the DRX configuration in use is one of the M sets of DRX configurations.

That is, the DRX Activation Command and the DRX Deactivation Command may multiplex one LCID value, and this time, may indicate whether the first MAC CE is the Deactivation Command together with the contents of the conforming portion. For example, the DRX configuration identifier indicated by the configuration identifier indication information carried in the index field included in the load part is any value exceeding the maximum range of the valid DRX configuration identifiers. Or the bits of the payload part take values of all 0's or all 1's, which indicates that the first MAC CE is a Deactivation Command.

It is to be understood that, if the payload part has a plurality of index fields, the first MAC CE may be indicated as Deactivation Command by setting the value of any one of the index fields to a special value.

As another example, the method shown in fig. 1 further comprises:

and if the value of the LCID domain corresponding to the first MAC CE is the first preset value and the values of the bits in the bitmap with the length of M carried by the load part carried by the first MAC CE are all third target values, deactivating the DRX configuration in use and entering a continuous monitoring state, wherein the DRX configuration in use is one of the M sets of DRX configurations.

The DRX Activation Command and the DRX Deactivation Command may multiplex an LCID value, and at this time, may indicate whether the first MAC CE is the Deactivation Command together with the contents of the conforming portion. For example, the values of the bits in the bitmap included in the payload portion are all 0 or all 1, indicating that the first MAC CE is the Deactivation Command.

In general, after receiving the control signaling of the network device, the terminal device needs to perform an acknowledgement response to the signaling of the network device while performing the relevant operation, so as to inform the network device that the signaling from the network device has been successfully received, and can start to perform the corresponding operation. On this basis, as shown in fig. 7, the method shown in fig. 1 further includes:

and S130, sending a second MAC CE, wherein the value of the LCID domain corresponding to the second MAC CE is a fifth preset value, and the second MAC CE is used for indicating that the first MAC CE is successfully received.

Optionally, in some embodiments, the second MAC CE does not carry the payload part, and the first MAC CE is a last MAC CE received before a transmission time of the second MAC CE.

That is, the network device may be informed by the MAC CE that no payload is carried that the most recently received DRX control signaling has been received.

However, in a normal situation, there may be a situation where multiple DRX control signaling is continuously transmitted in a short time, and since the situations of Hybrid Automatic Repeat request (HARQ) transmission or retransmission are different, there may be a confusion situation that the transmission is performed first and then the transmission is performed first, and even an analysis error between HARQ NACK and HARQ ACK may occur, which may result in that the signaling confirmed by the terminal device cannot be accurately determined. In this case, the terminal device may carry the payload portion in the second MAC CE, and information carried by the payload portion carried by the second MAC CE is used to indicate the first MAC CE.

For example, the load part of the second MAC CE carries an index of the target DRX configuration that the first MAC CE indicates to activate, or the second MAC CE indicates, in the form of a bitmap, the index of the target DRX configuration that the first MAC CE indicates to activate, or the load part of the second MAC CE carries specific deactivation information, etc., which may specifically refer to the related description of the load part of the first MAC CE throughout the text and is not described herein again.

On the basis of all the above embodiments, the M sets of DRX configurations include a default DRX configuration, as shown in fig. 8, the method shown in fig. 1 further includes:

and S140, if the preset condition is met, activating the default DRX configuration.

The preset condition in S140 may be configured by the network device through RRC signaling. The preset conditions may be, for example: no uplink or downlink transmission is satisfied for a certain duration, or the duration of no uplink or downlink transmission is satisfied for a preset number of currently used DRX cycles (or for a specified DRX cycle length).

And S150, executing DRX operation according to the default DRX configuration.

Optionally, in some embodiments, the DRX operation is performed according to a default DRX configuration, including: starting to use the default DRX configuration from the next DRX period after the moment when the preset condition is met is determined, and executing DRX operation; or, if the moment meeting the preset condition is determined not to be the starting moment of the continuous monitoring timer corresponding to the DRX configuration in use, starting to use the default DRX configuration from the moment meeting the preset condition, and executing DRX operation.

For example, for the terminal device, since there is no uplink and downlink transmission, the terminal device does not start any DRX timer related to transmission, the DRX-inactivity timer is not started, the terminal device may be at the start boundary of the DRX-on duration timer, and then the terminal device performs DRX operation according to the default DRX configuration from the next DRX cycle. Or the terminal device is not at the start boundary of the DRX-onDurationTimer (e.g., the preset condition is that no accumulated duration of data transmission exceeds the duration threshold), the terminal device immediately performs the DRX operation according to the default DRX configuration, or performs the DRX operation according to the default DRX configuration from the next DRX cycle start boundary.

Further, after the terminal device activates the default DRX configuration, the network device needs to be informed of the behavior. The method shown in fig. 1 further comprises: and transmitting a third MAC CE, wherein the third MAC CE is used for confirming that the default DRX configuration is activated by the terminal equipment through the network equipment. Because the network device does not issue any DRX control signaling and monitors the uplink and downlink transmission behaviors of the terminal device, the network device can directly understand that the terminal device activates default DRX configuration after receiving the third MAC CE.

As an example, the value of the LCID domain corresponding to the third MAC CE is a sixth preset value, or it may be understood that the value of the LCID domain corresponding to the third MAC CE is different from the values of the LCID domains corresponding to the first MAC CE and the second MAC CE.

As another example, the value of the third MAC CE field is the same as the value of the LCID field corresponding to the MAC CE indicating that the first MAC CE has been successfully received, and the value of the reserved bit corresponding to the third MAC CE is a seventh preset value; or the value of the LCID field corresponding to the third MAC CE is the same as the value of the LCID field corresponding to the MAC CE used for indicating that the first MAC CE has been successfully received, and the third MAC CE carries a load part, where information carried by the load part is used for indicating the default DRX configuration.
